KY-010 Photo switch Module, Photo Interrupter Module

The KY-010 Photo Interrupter module is a switch that will trigger a signal when light between the sensor’s gap is blocked.
This module consists of an optical emitter/detector and 3 male header pins on the front. On the back there are two resistors of 1kΩ and 33Ω.

The sensor uses a beam of light between the emitter and detector to check if the path between both is being blocked by an opaque object.

Operating Voltage    3.3V ~ 5V
Board Dimensions     18.5mm x 15mm [0.728in x 0.591in]
